BCL2 and cancer: Srivastava et al. [53] found in an extensive study using several cancer cell lines that QRC is capable of triggering apoptosis in this kind of cell and, by Western blotting Nalm6 cells treated with QRC at different concentrations (0, 10, 20 μM for 24 h), found a level increase in apoptotic markers like p53 and MCL1 and a decrease in anti-apoptotic proteins such as BCL2 and BCL-xL.
